BOLT FOR RIM-.LATCHES.

Specification of Letters Patent.

Patented Jan. 1, 1907.

Application filed January 12, 1905. Serial No. 240,805.

To all whom it may concern:

Be it known that 1, WILLIAM A. MARBAOH, a citizen of the United States, and a resident of Cleveland, county of Ouyahoga, and State of Ohio, have invented certain new and useful Improvements in Bolts for Rim-Latches, of which the following is a specification and which are illustrated in theaccompanying drawings, forming a part thereof.

The object of the invention is to provide a ,bolt for that type of door-latches commonly known as the rim-latch, which shall be struck up out of sheet metal and shall be hollowed or channeled longitudinally.

A further object is to provide in a reversible latch of sheet metal integral shoulders for the engagement of the spindle-arms.

The invention consists of the structure hereinafter described, and which is illustrated in the accompanying drawings, in which Figure 1 is a longitudinal section of the latch, taken on the line 1 1 of Fig. 3. Fig. 2 is a front elevation of the latch. Fig. 3 is a plan section on the line 3 3 of Fig. 1. Fig. 4 is a detail of a slightly-modified form of the bolt shown in Figs. 1, 2, and 3. Fig. 5 is a blank from which this form of bolt is struck. Fig. 6 is a detail of a further modification. Fig. 7 is a blank fromwhich the last-named bolt is formed. Fig. 8 is a detail of another modification, and Fig. 9 is .a blank from which the latter bolt is formed.

Referring to the form shown in Figs. 1, 2, and 3, there appears at 10 the usual casing having lateral Wings 11 11, through which screws may be passed for securing the latch to a door; at 12, an oscillatory handpiece or spindle having a shank 13, which projects through the casing and carries lateral arms 14 14 for controlling the bolt, a guide-plate 15 lying against the inner face of the cover of the casing and extending laterally across the chamber thereof, being apertured to receive the stem of the bolt and serving as an abutment for the spring 16 which throws the bolt forward.

. The bolt 17 is formed of a single piece of sheet metal. (Shown in blank form at 18, Fig. 5.) The wings 19 19 of the blank are folded downwardly and inwardly to form the side walls 20 21 and the bottom wall 22 of the bolt-head. These Wings may be of such length that their edges will meet, as shown at 33, Fig. 4, or they may be somewhat shorter, leaving a longitudinal channel through the bottom wall 22, as shown in Fig. 2.

downwardly along the dotted line 23 to form the rear wall 24 of the bolt, from the lower portion of which extends the stem of the bolt. (Shown in the blank, Fig. 5, at 27.) From this stem portion there project laterally and backwardly a pair of wings, (shown in the blank, Fig. 5, at 25 26,) and these wings and the stem portion have their edges turned up to give them channel form. The ends of the wings 25 26 are folded upwardly along the dotted lines 28 29, Fig. 5, forming the shoulders 30 31, adapted for engagement by the lateral arms 14 14 of the spindle 12. The spring 16, already referred to, is coiled around the stem 32 of the bolt, and the end of this stem is inserted and plays through an aperture in the guide-plate 15.

The bolt thus far described has its front end open. If desired, this end may be closed by forming on the blank an extension 51, which may be folded downwardy, as shown in Figs. 6 and 7, or the blank, as shown at 57 in Fig. 9, may have a pair of wings 55 projecting obliquely from its head, and these wings may be, folded inwardly along the dotted lines forming the juncture of their bases with those portions of the blank which will form the side walls of the bolt. When the laterally-extended portions of the blank are folded downwardly to form the side walls of the bolt-head, the edgesof the wings 55 will meet along the longitudinal median line of the face of the bolt and their upper edges will meet the forward edge of the top wall. The lateral wings of the blank are preferably of such length that they may be folded inwardly and will meet to form the bottom wall, all as plainly shown in Fig. 8.

The bolt in any of'the described forms is longitudinally channeled, is very light and strong, and being made of sheet metal is very cheap of construction.

I claim as my invention- 1. A latch-bolt formed of sheet metal, the

'side walls of its head extending downwardly from and being integral with its back and being extended across the front end of the bolt, the bolt having lateral shoulders which are integral with its shank and have upturned edges.

i .The body portion of the blank is bent 'IOO blank havmgz two" pairs of'lateral Wingsl; one wardly. v

pair ofwin s being turned downwardy to form the si e Walls of the head of the bolt, WILLIAM MARBAOH' 5 the blank-body being folded downwardly Witnesses:
